Troopers said in a Monday dispatch that the mauling of 77-year-old Glenn Bohn, near Mile 68 of the highway, was first reported at about 1:30 p.m. Friday.

"The bear was subsequently killed by a hunting partner on scene," troopers wrote. "Bohn was driven to the Denali Highway by snowmachine where he was flown by LifeMed (air ambulance) to Anchorage."

Troopers spokesman Tim DeSpain said Bohn and his partner had been hunting bear at the time of the attack. There wasn't immediate word on the circumstances leading up to the mauling or Bohn's current condition.

"What was reported to troopers sounded like his injuries were pretty significant," DeSpain said.

Alaska Department of Fish and Game spokesman Ken Marsh said a Fish and Game biologist had flown to the area with Alaska Wildlife Troopers, but couldn't land due to snow conditions. Wildlife troopers conducted an examination of the bear's carcass.

Troopers said the bear's remains were harvested and removed from the field.
